Your ROOT_URL in app.ini is http://git.osmesh.ru/ but you are visiting http://91.221.70.94:3000/MOS/OpenBoard/blame/commit/35e784eb1a1b31e055662d92da584141ece03ff5/resources/etc/npapi-wrapper.application.x-shockwave-flash.swf.htm
You should set ROOT_URL correctly, otherwise the web may not work correctly.
